Case 45：The Grasping Car V2
In the previous case we built a grabbing car which can grasp objects very well, but it is not able to turn. We use Nezha Inventor's Kit to build a car that can both turn and grab objects here, the obvious feature in this case is that only one servo is applied to realize both the functions of lifting, lowering and grasping objects by the mechanical claw.
Quick to Start
Build it as the assembly steps suggest:
Click "Advanced" in the MakeCode drawer to see more choices.
For programming Nezha Breakout Board, we need to add a package. Search with "Nezha" in the dialogue box and click to download it.
Notice: If you met a tip indicating that some codebases would be deleted due to incompatibility, you may continue as the tips say or create a new project in the menu.
Code as the picture suggests
